PLUMBING STRUCTURE.

Specification of Letters Patent.

Patented Jan. 23, 1917.

Application filed April 26, 1916. Serial No. 93,579.

To all whom it may concern.-

Be it known that I, OHARLns F. MADDEN, a citizen of the United States, residing at Green Bay, in the county of Brown and State of IVisconsin, have invented certain new and useful Improvements in Plumbing Structures, of which the following is a specification.

My invention relates to improvements in plumbing structures.

One of the objects of my invention is to provide a structure combining a trap, settling basin, floor drain and a manually-op erable, positive valve in one leg of the trap adapted to be raised above the opening connecting the settling basin, to control communication between the trap and the drain outlet in said basin.

Other and further objects of my invention will become readily apparent to persons skilled in the art from a consideration of the following description when taken in conjunction with the drawings, wherein Figure -1 is a central, vertical section through the structure. Fig. 2 is a section taken on line 22 of Fig. 1.

In both the views the same reference characters are employed to indicate similar parts.

This is an improvement of the structure disclosed and claimed in my Patent No. 1,007,463 dated October 31st, 1911, wherein an automatic valve is provided between one leg of the trap and the settling basin adapted to be automatically closed when the sewage backs up through the trap to prevent flooding of the room in the floor of which the fixture is placed.

In my present invention I have provided a somewhat similar structure with a positively closable valve in one leg of the trap, leaving a clear, full passage through the trap to the settling basin when the valve is open, thereby to carry away relatively large pieces of solid matter, such as matches or the like, and prevent clogging and at the same time provide a more positive means to prevent the backing up of sewage, through the trap and into the room, through the settling chamber.

In the illustrative embodiment 3 is one leg of the trap to be connected at its terminal end 4: to a sewer. The trap consists of a pipe bent upon itself, as at 5, into another parallel, vertically extending leg 6. The leg .6 is provided with a laterally extending opening 7 near its top, to which the settling basin 8 is detachably to be secured. The opening 9 from the settling basin 8 may be connected bv a pipe to a similar basin located in another part of the floor, if desired, or it may be closed by a cap or plate.

The leg 6 is provided with an extension 10, terminating in a flange 11. The settling basin 8 is provided with a circular rim 12 for engagement-with the flange 11 of the trap. Studs 13, having their heads cast in the flange 12 are thereby permanently fixed in the body part thereof and project sufliciently therefrom to pass through the flange 11, on the trap, and to include the nuts 14 for holding the parts together, so that the settling basin may be easily and quickly removed, from above, when desirable. Thesettling basin is provided with a removable perforate top 15, the upper surface of which is designed to be placed in practically the same longitudinal plane with the floor in which the device is used. The top or cover 15 is easily removable so that the basin 8 may be conveniently cleaned.

Inside of the leg 6, of the trap, is an annular, internally projecting flange 16 providing a seat to be covered by the valve 17. The valve is connected to a. valve stem 18, screw threaded as at 19 into a screwthreaded top, or cover 20, insertible in the upper end of the leg 6.

To the upper end of the valve stem 18 is secured a hand wheel 21 for rotating the valve stem and closing the valve 17 upon the seat 16. The dotted lines show theopen position of the valve and the, valve moving parts when the trap and the basin are in free communication with the sewer. The valve when open is raised above the opening 7, as shown. In the event that the sewer water should back up, or in the fear of such a contingency, the valve 17 is closed upon its seat 16 by rotation of the valve stem 18, so as to shut ofi' communication between the settling basin and the trap. If water has already backed upinto the compartment in which the device is situated, the positively closing valve 17 willprevent further ingress of the objectionable liquid and other matter into the room while that which has already passed therein is being removed.

When the device is to be used intermit tently the valve 17 may be normally maintained closed except when in use, thereby positively cutting off possibility of gases A plumbing fitting comprising a pipe returned upon itself to provide two parallel legs of a trap, one leg extending vertically and open at its upper end, a settling basin connected to the vertically extending leg below its upper end, an annular ledge formed on the inner wall of the vertically extending leg below its connection with the settling basin, a cap secured in the upper end of the said leg, a screw threaded rod taking through said cap, and a valve disk carried by the lower end of the rod for cooperation with the said annular ledge.

In testimony whereof I hereunto set my hand in the presence of two subscribing witnesses.
